In this case, since the suspension stress is distributed and loaded on both sides of the roof panel P, the panel P group can be suspended without difficulty in the insertion leg 21 of the mounting hardware 1 without any fear of occurrence of bending stress or the like. Therefore, if the roof beam 5 and the mounting hardware 1 are appropriately designed and constructed, even the permanent fixing of the roof panels P to each other by the band hardware as shown in FIG. 4C can be omitted.

When fastening the mounting hardware 1 to the roof panel P, it is preferable to fix the face plate 3 of the mounting hardware to the inner surface of the rafter 4 (claim 9). If the face plate portion 3 is fixed to the inner surface of the rafter 4, the outer surface of each rafter 4 on both sides of the roof panel P is only the surface of the smooth rafter 4, so that each panel P is connected and erected on the roof beam 5. In this case, each panel P can be erected in a close contact form without any gap, and the roofing material can be supported smoothly, so that a high quality roof can be obtained.

Further, the roof beam 5 sandwiches a plurality of short interposed plates 53 between two long beam plates 51 and 52 by forming an insertion portion 50 of the space S at each interposed plate end 53E. It is convenient to form a three-layer form in which it is attached and integrated (claim 10). In this case, the beam plates 51 and 52 and the interposed plate 53 can be made of wood, plywood, a metal plate, or the like. Processing can be carried out efficiently at the factory as standard products. Also, by arranging and forming the space S so that various roof panels P can be applied, a versatile roof beam 5 can be formed.
